Abstract
With the gradual development of applications on solar photovoltaic, the "PV power plant construction stage" has transited to the "PV power plant operation stage" in China. In the most process of the solar photovoltaic, it is frequent that the decrease of the photovoltaic system efficiency and economic benefits always occurs, which are caused by the fouling on the surface area of the photovoltaic modules. And it has attracted the attention of the experts and scholars in this area. In this paper, through investigating the application status in photovoltaic station and the research status in fouling problems, the power generation situation of the practical projects on the clean and fouling monolithic solar panels is comparatively analyzed. So as to quantitatively analyze the influence extent of the fouling on photovoltaic power generation efficiency. And a kind of mechanized, automated cleaning device is developed, and the improving method of this problem is put forward.
